PulsatingQuasar : I know, the faster the better, but my financial resources are not so wide to get me a CPPC or even a MK3 040 :-) But I remember that when I had an A1230 and installed a Zorro4 busboard with a CV64/3D that the general speedup was bigger than I first expected it to be, mainly due to the fast screen acceleration, so I guess it´s the same as when you would install a Prom in an A4000D with a humble 68030/25. Am I wrong ?? Please correct me if I am, still need to learn a lot :-D
